# ChatGPT

> 🚧 **Prototype**
> 
> 
> The Dataddo MCP server is an early prototype. See the [Dataddo MCP Server overview](/docs/dataddo-mcp-server) for its current capabilities and roadmap.

Connect the [Dataddo MCP server](/docs/dataddo-mcp-server) to [ChatGPT](https://chatgpt.com) as a custom connector using ChatGPT's **developer mode**.

> ⚠️ **Authentication limitation**
> 
> 
> ChatGPT custom connectors support **OAuth, No Authentication, and Mixed Authentication** - they cannot send a static API token header. For now, connect to the Dataddo MCP server **without authentication**, which limits you to tools that do not access account data (such as `current-time`). Support for authenticated access from ChatGPT is planned.

## Prerequisites

- A ChatGPT **Pro, Plus, Business, Enterprise, or Education** account. Custom connectors are available on the web app only.
- Developer mode enabled: go to **Settings → Security and login** and toggle **Developer mode** on.
- On Business and Enterprise workspaces, a workspace admin may need to allow creating custom MCP connectors first.

## Setup

1. In ChatGPT (web), open **Settings** and go to the connectors/apps section.
2. Click the **+** button to add a new connector.
3. Fill in:
  - **Name:** `Dataddo`
  - **MCP server URL:** `https://headless.dataddo.com/mcp`
  - **Authentication:** No Authentication
4. Confirm. Dataddo's tools appear on the connector's detail page, where you can toggle individual tools on or off.

## Try It Out

Start a new chat, enable the Dataddo connector for the conversation, and ask:

> Using the Dataddo tools, what is the current time in UTC?

## Troubleshooting

- **The connector option is missing.** Confirm your plan supports developer mode, that it is toggled on, and (for Business/Enterprise) that your workspace admin has allowed custom connectors.
- **Connection fails.** Verify the URL is exactly `https://headless.dataddo.com/mcp`.
